Wise Guys

The Wise Guys were a German a cappella band that was formed in 1990 in Cologne, Germany and split in 2017. History of the group Apart from Nils Olfert and Björn Sterzenbach, the members all attended the Hildegard-von-Bingen-Gymnasium in Cologne from 1981 to 1990. With their schoolmates Clemens Tewinkel and Christoph Tettinger, who also founded a brass band with them, they formed a rock band. At a school event, the band performed a single a cappella song. After graduating from high school with their A-levels (Abitur) in 1990, the group focussed on the a cappella genre. They soon named themselves the "Wise Guys". Eddi (Edzard) joined an 18-month alternative service for conscientious objectors in Brussels, which left the group as a quartet. The remaining four joined the Ersten Kölner Barbershop Choir. In early 1994, the group placed third in a Barbershop Quartet competition. However, this type of music was not representative of their later work. In April 1995, Ferenc Husta joined the group as the bass voice, replacing Christoph Tettinger, who could no longer sing for professional reasons. Christoph Tettinger instead became the group's manager.
